IBEER-TPRESERVER.

To all whom it may concern:

Be it known that I, CHRIS BERGSVIK, a citizen of the United States, residing at Yankton, in the county of Yankton and State of South Dakota, have invented certain new and useful Improvements in Beer- Preservers; and I do hereby declare the fol I lowing to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to beer preservers or beer-pressure apparatus. Its object is to provide a device which shall constantly maintain the pressure during the dispensing of the beer and thus preserve the constant gaseous pressure necessary to keep the beer from staling.

To this end it comprises the combination of parts especially recited in the claims thereto appended.

In the drawings Figure 1 represents in perspective my device with the parts sepa rated to more clearly indicate their mode of connection with the barrel. Fig. 2 is a central vertical section. Fig. 3 is a partial section with the beer-pressure apparatus shown in full, the whole being reversed for use. Fig. 4c is a detail of the closure with its connecting link.

1 represents a barrel. Secured to the head of the barrel is a flanged ring 2 surrounding an opening in the head of the barrel. The ring 2 has a recess 3 into which fits a flanged rim of a closure 4. The closure has, in the form illustrated, a central flange across which lies a rod 6 engaged by a supporting hook 7 screw-threaded at the upper end.

Within the ring 2, and preferably integral therewith, is a shoulder 8 which forms a support and bearing for a bar 9. The bar 9 is centrally perforated and screw-threaded so that it may operate upon the screwthreaded shank of the supporting hook 7, and when turned down upon the shank will bring up the closure 4 tightly against the bottom of the ring 2. The ring 2 has, as illustrated, an upwardly extending flange 10. This flange 10 serves as a support for a recessed bottom flange ll of a cylinder 12, which serves as a storing vessel for a gasbag 13, and later, when the gas-bag is not in place within the cylinder 12, as a passage for the beer.

The gas-bag 13 is secured by a connection Specification of Letters Patent.

14: to an air-pipe 15, which communicates by a valved connect-ion with a source of air supply. On the thread-ed bottom of the pipe 15 is screwed a plate 16, which serves, when the pipe 15 is pushed down, to force the gasbag out of the cylinder 12. Extending from the top of the cylinder 12 is a smaller cylinder 17 having a stuffing box 18 at the top through which the pipe 15 plays, and having a valved beer discharge 19 in the side.

20 represents ears on the side of the cylinder 12, which carry on each side swiveled connections 21, each having a swinging bottom arm 22, which takes into and under re cessed lugs 23 on each side of the ring 2 and thus serve to securely hold the device adjustably and removably in place upon the barrel head. The arm 22 has a threaded head which enables it to be adjusted and the upper arm of the swiveled connection is also secured by a nut and threaded end.

24. represents a screwthreaded rod which passes through the head of the cylinder 12 and which, when turned by means of a wrench applied to its polygonal head, will serve to force down the closure 4 after the bar 9 has been removed and the parts assembled.

In operation the barrel 1 is filled with beer, the closure having been brought tightly up against the gaskets of the ring 2 by screwing down the bar 9, upon the threaded head of the hook 7. When my device is to be applied the bar 9 is removed, the closure being held temporarily in place by the pressure in the barrel. Then the cylinder 12 and its parts are secured in place upon the ring 2 by bringing the arms 22 into engagement with the recessed lugs 23 and tightening the parts. The rod 2 1 is then screwed down, pushing upon the closure 4 and forcing it out of place so that it falls to the bottom of the barrel. Then the sliding air-pipe 15 is forced down, its attached plate 16 pushing the rubber bag ahead until the bag is within the barrel. Then the barrel and device are reversed and connected with any desirable apparatus for dispensing the beer. Air or gas-pressure is admitted through the pipe 15 and as the beer is drawn off the air-pressure constantly distends the bag 13, thus maintaining the pressure uniformly within the barrel and keeping the beer fresh, that is, preserving it.

I claim 1. In a beer-pressure apparatus, the con1- bination of a receptacle having an opening, a closure for the opening, a cylinder adapted to be secured above the opening, a slidable gas-pipe passing through the cylinder and bearing a gasbag at the bottom, and means for forcing the closure out of the opening when the cylinder is in place.

2. In a beer-pressure apparatus, the combination of a receptacle having an opening, a closure for the opening, a cylinder adapted to be secured above the opening, a slidable gas-pipe passing through the top of the cylinder and bearing at the bottom a plate and beneath the plate a gas-bag.

3. In a beer-pressure apparatus, the combination of a receptacle, a closure, a cylinder adapted to be secured above the closure, means carried by the cylinder for forcing the closure out of the opening, an air or gas-pressure supply passing through the cylinder, and a discharge for the beer through the cylinder.

4. In a beer-apparatus, the combination of a receptacle having an opening, a ring for the opening having bearing flanges and shoulders, a closure and devices for support ing the closure from the ring, a cylinder, means for securing the cylinder to the ring,

a gas-bag and an air-supply, the gas-bag when out of operation being stored in the cylinder, means for forcing the gas-bag out of the cylinder through the opening, and means for dispensing the beer.

5. In a beer-apparatus, the combination of a receptacle having an opening, a ring within the opening bearing a closure, a cylinder serving as an air-supply and beer discharge passage and adjustable swiveled connections for securing the cylinder upon the ring, and means for removing the closure when the parts are assembled.

6. In a beer-pressure apparatus, the combination of a receptacle having an opening, a closure for the opening, a cylinder secured to the receptacle above the opening, a gassupply and beer-discharge means, and a screw-threaded rod passing through a screw-threaded opening in the top of the cylinder and operable to remove the closure.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses. 7
